Given numbers are 642, 801, 267, 560

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 801 are 3 x 3 x 89

Prime factors of 267 are 3 x 89

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 642, 801, 267, 560

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(642, 801) = 171414

GCD(642, 801) = ( 642 x 801 ) / 171414

= 642 / 801

= 642

Step2:

LCM(3, 267) = 267

GCD(3, 267) = ( 3 x 267 ) / 267

= 3 / 267

= 3

Step3:

LCM(3, 560) = 1680

GCD(3, 560) = ( 3 x 560 ) / 1680

= 3 / 560

= 3

So, Greatest Common Divisor of 642, 801, 267, 560 is 1
